REGENERATIVE GAS STOVE.

SPECIFICATION forming part of Letters Patent No. 319,438, dated June 9, 1885.

Application filed April 28, 1884. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. BAKER, of the city of Philadelphia and State of Pennsylvania, have invented anew and Improved Gas-Stove, of which the following is a specification.

My invention relates to gas-stoves in which radiating-tubes are employed to impart heat to the surrounding atmosphere; and it consists of a series of such tubes placed beneath and connected with a central chamber around which are arranged gas-tubes,the whole structure above the radiating-tubes being inclosed within a second chamber or casing whereby the gas-tubes are heated and the products of combustion are drawn downward through said central chamber and through said series of radiating tubes to the draft-pipe, said con struction combining in one structure a powerful lamp and a heat-imparting stove.

In the accompanying drawings, in which similar letters of reference denote like parts in the several figures- Figure I is a vertical section through the center of the apparatus, showing the arrangement of the several parts Fig. II, a transverse section through the line a a, Fig. I; and Fig. III, a transverse section through the line b I), Fig. I.

Upon aframe-work or stand (indicated at M) is supported a cylindrical chamber, E, open at the bottom to admit air, which passes upward to the top of the structure, where are located the gas tubes and jets e e 0.

Within the lower part of the chamber E is supported a central chamber, A, communicat ing only by means of two or more pipes, l? P, with an annular pipe, 0 the latter being the first of a series of radiating-tubes.

Below the chamber A is an extension or outer casing, H, inclosed and serving as a gas-supply chamber, into the top of which are secured the gas-tubes e e.

A. pipe, G, serves as a conduit for the gas to the chamber H.

An additional or outer shell, open at the bottom, and which is a support for the chimney L, serves as a draft-pipe through which fresh air is drawn upward to the flame.

It is desirable, and indeed essential, that the central metal chamber should be extended upward considerably beyond the top of the gas tubes or jets, and in order to prevent the upper edges of the same from being burned away by the powerful flame surrounding and passing over and down through the same I add an extensionpiece of porcelain having a ribbed base, 0, serving to spread the flame outward.

At the base of the apparatus is placed a second annular radiating-pipe,D, and between it and the upper pipe, 0, is arranged a series of upright radiatingtubcs, It R, opening into each of the pipes O and D, and to the lower pipe, D, a draft-pipe, S, is secured, leading to the chimney.

The operation is as follows: Gas is supplied through the pipe G to the gas chamber H, through which it passes to the tubesc e,which are supplied with proper burner-tips, and air is supplied through the chamber E, passing upward to the region of the gas-j et-s. When the gas is ignited, the heat will draw up the supply of fresh air, the flame will spread upward and give a bright and strong light, and the products of combustion of the mingled gas and air will be drawn downward by the draft through the central chamber and through the radiating-tubes. In consequence of such action the gas and air will be highly heated and expanded from the heat given off from the hot surfaces of the chamber A, and the external radiating-tubes, O, R, and D, will in like manner give off great heat to the surrounding atmosphere and perform all the functions of a heating-stove.

It is apparent that the radiating-tubes may be varied in number, form, and arrangement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas-stove consisting of a central fluechamber closed at its base and a series of gas tubes and jets surrounding the same, in com= bination with a series of upright radiating flue-tubes arranged below said central chamher and connected therewitluwhereby the products of combustion of the ignited gas are drawn down through said central chamber and said flue-tubes and impart heat therefrom by radiation to the surrounding atmosphere, substantially as set forth,

2. A gas-stove for producing both light and heat, consisting of two central flues placed one within the other and affording an airpassage iOO 3. The combination, in alight and heat producing stove, of the radiating-tubes O, D, and l 3 R, the gas-chamber H, the chambers A and E, gas-tubes e e, extension-tube c, and chimney L, the whole being constructed and arranged substantially as and for the purpose set forth.

In testimony whereof I have signed my name 2c to this specification in presence of witnesses.

JOHN W. BAKER.
